Description of the Related Art

Apoptosis is a process of programmed cell death that occurs in multicellular organisms. Through apoptosis, cells commit suicide as a way to clear unwanted or damaged cells or to prevent uncontrolled growth. Thus, apoptosis plays an essential role in tissue development and function. Dysregulation in the apoptotic pathway, for example decrease or increase in apoptosis, can lead to a number of diseases and conditions, for example, cancers, autoimmune diseases, inflammatory diseases, and infections.

Human Subject Identification

The present disclosure relates to methods of treating alteration in gene expression (e.g., age-related or non-age-related alteration). It has been shown that the expression level of a number of genes, such as ones playing important roles in cell growth and apoptosis regulation, is decreased or downregulated in aging human beings (Glass et al. Genome Biology 2013, 14:R75, the content of which is hereby incorporated by reference in its entirety). Gene expression changes also play important roles in aging and serve as biomarkers of physiological decline and disease conditions, such as Alzheimer's disease. Decreased gene expression levels, due to accumulation of DNA damages, were observed in the human brain (Lu et al. Nature 429, 883-891 (24 Jun. 2004), the content of which is hereby incorporated by reference in its entirety).

Therefore, disclosed herein are methods of treating a human subject having an age-related decrease or downregulation in gene expression levels, such as those genes associated with the apoptosis pathway. In some embodiments, the human subject can be identified based on the human subject's age, gene expression level, family history, health conditions, medical history, habits, or a combination thereof.

Regardless of the cause of the downregulation, some common terminology can be used. In some embodiments, the expression level of a gene (such as Cd5l, Perp, Unc5b, Bag5 or Bri3) in a human subject is considered to be downregulated or decreased if the decrease in the expression level of that gene is statistically significant compared to that of a control or a reference. The control or reference can be, for example, a normal healthy population, a population at large, a collection of individuals of the same age or condition or sex, or the same human subject at a different time (e.g., at an earlier time of life when the human subject does not have the disease or condition that results in the downregulation).

In some embodiments, a normal healthy population or a population at large can be a population having the same or similar gender, age, and/or race, compared to the human subject. In some embodiments, the expression level of the gene in the control or reference can be the mean or median expression level of the gene in control subjects in the control or reference subjects in the reference. The decrease in expression level can be statistically significant if the probability of the observed difference occurring not by chance, the confidence level, is greater than a threshold. The threshold can be, or be about, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.9%, or a number or a range between any two of these values.

In some embodiments, the decrease in expression level can be, or be about, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or a number or a range between any two of these values. In some embodiments, the decrease in expression level can be at least 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more.

In some embodiments, the human subject may have an age that is, is about, is over 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, or 100 years old.

In some embodiments, the human subject is identified based on the human subject's expression profiles of one or more genes associated with the apoptosis pathway. Non-limiting exemplary methods for determining the human subject's expression profiles include: amplification techniques such as PCR and RT-PCR (including quantitative variants), hybridization techniques such as in situ hybridization, microarrays, blots, and others, and high throughput sequencing techniques like Next Generation Sequencing (Illumina, Roche Sequencer, Life Technologies SOLID™), Single Molecule Real Time Sequencing (Pacific Biosciences), True Single Molecule Sequencing (Helicos), or sequencing methods using no light emitting technologies but other physical methods to detect the sequencing reaction or the sequencing product, like Ion Torrent (Life Technologies). Non-limiting exemplary methods for determining the human subject's expression profiles include: binding techniques such as ELISA, immunohistochemistry, microarray and functional techniques such as enzymatic assays.

Genes of Interests

In some embodiments, administering to the human subject the effective amount of the nitroxide antioxidant results in an increased expression level of a gene, for example a gene associated with the apoptosis pathway. Therefore, some embodiments disclosed herein provide methods for treating an individual in need thereof, comprising administering to an individual an effective amount of a nitroxide antioxidant to increase the level of expression of a gene (e.g., a gene associated with the apoptosis pathway). In some embodiments, the methods further comprise: identifying the individual. In some embodiments, the individual has a disease-related decreased expression level of the gene (e.g., a gene associated with the apoptosis pathway). Some embodiments disclosed herein provide methods for treating an individual in need thereof, comprising administering to an individual an effective amount of a nitroxide antioxidant to increase the level of expression of a gene (e.g., a gene associated with the apoptosis pathway). In some embodiments, the methods further comprise: identifying the individual. In some embodiments, the individual is in need of an increased expression level of the gene (e.g., a gene associated with the apoptosis pathway).

Non-limiting examples of diseases associated with altered level of apoptosis include cancer; breast cancer; lung cancer; kidney cancer; cancers of the ovary and uterus; cancer of the central nervous system; cancers of the head and neck; melanoma; lymphomas; leukemia; neurological disorders; Alzheimer's disease; Parkinson's disease; Huntington's disease; amyotrophic lateral sclerosis; stroke; cardiovascular disorders; ischemia; heart failure; infectious diseases; bacterial infections; viral infections; autoimmune diseases; systemic lupus erythematosus; autoimmune lymphoproliferative syndrome; rheumatoid arthritis; and thyroiditis.

Non-limiting exemplary genes involved in the apoptosis pathway include those involved in the extrinsic apoptosis pathway (FAS, FASLG, TNFRSF10A, TNFRSF10B, TNFRSF10C, TNFRSF10D, TNFRSF11B, TNFSF10, TNFRSF1A, TNF, FADD, CFLAR), those in the Caspases family (CASP1, CASP2, CASP3, CASP4, CASP5, CASP6, CASP7, CASP8, CASP9, CASP10, CASP14), those in the IAPs family (NAIP, BIRC2, BIRC3, XIAP, BIRC5, BIRC6, BIRC7), those involved in the mitochondrial/intrinsic apoptosis pathway (Bcl-2 family: BCL2, MCL1, BCL2L1, BCL2L2, BCL2A1, BCL2L10, BAX, BAK1, BOK, BID, BCL2L11, BMF, BAD, BIK, HRK, PMAIP1, BNIP3, BNIP3L, BCL2L14, BBC3, BCL2L12, and BCL2L13; and other proteins: APAF1, CYCS, DIABLO, HTRA2, AIFM1, and ENDOG).

The gene associated with the apoptosis pathway can be Cd5l, Perp, Unc5b, Bag5 or Bri3. For example, the treatment can result in increased expression levels of Cd5l, Perp, Unc5b, Bag5, Bri3, or any combination thereof. The increased expression levels of Cd5l, Perp, Unc5b, Bag5, Bri3, or any combination thereof, can increase the level of apoptosis. The increased level of apoptosis can result in a decrease in or disappearance of signs and symptoms of a disease associated with decreased apoptosis, including the curing of the disease associated with decreased apoptosis. In some embodiments, the increased expression levels of Cd5l, Perp, Unc5b, Bag5, Bri3, or any combination thereof, can decrease the level of apoptosis. The decreased level of apoptosis can result in a decrease in or disappearance of signs and symptoms of the disease associated with increased apoptosis, including the curing of the disease associated with increased apoptosis.

Cd5l

Cd5l is also known as apoptosis inhibitor of macrophage (AIM), Spα, and apoptosis inhibitor 6. Higher Cd5l levels have been observed in younger people, especially in women (Yamazaki et al., PLoS One. (2014) 9(10):e109123, the content of which is incorporated by reference in its entirety). Thus, estrogen can be involved in the increase in circulating Cd5l levels. Consequently, up-regulation of Cd5l by, for example, a nitroxide antioxidant can prevent and counteract diseases (e.g., age-related diseases) caused by or associated with lower Cd5l levels.

Cd5l participates in macrophage homeostasis, including macrophage survival by inhibiting apoptosis. Macrophages play a major role in host innate defense. They can be found in tissues, for example, that function in the filtration of blood or lymph fluids, including liver, spleen, lung, and lymph nodes. Macrophages recognize, internalize, and destroy endogenous and foreign substances that may be harmful Inflammation is a major mechanism to protect organisms from damage in responding to pathogen infection and tissue injury. Cd5l acts as an inhibitor of apoptosis in macrophages and promotes macrophage survival from the apoptotic effects of oxidized lipids in case of atherosclerosis (PubMed:9892623; PubMed:16054063; the content of each is incorporated herein by reference in its entirety).

Cd5l is an immune regulator that inhibits immune cell apoptosis at the inflammatory sites and functions as a modulator in immune response. Cd5l has been shown to be involved in pattern recognition of bacteria and in the modulation of monocyte inflammatory responses (Sarrias et al., J. Biol. Chem. (2005) 280:35391-35398, the content of which is incorporated by reference in its entirety). Cd5l is also involved in early response to microbial infection against various pathogens by acting as a pattern recognition receptor and by promoting autophagy (by similarity). Cd5l has been shown to potentiate the antimicrobial response against Mycobacterium tuberculosis by enhancing autophagy (Sanjurjo et al., LoS One. (2013) 8(11):e79670, the content of which is incorporated by reference in its entirety). Cd5l has been shown to inhibit apoptosis of T cells and natural killer T (NKT) cells from Corynebacterium parvum-induced liver granulomas (Kuwata et al., Comp. Hepatol. (2004) 3, Suppl. 1:S44, the content of which is incorporated by reference in its entirety). Cd5l has been shown to prevent apoptosis of CD4±CD8+(CD4/CD8) double-positive thymocytes induced by dexamethasone and γ-irradiation awaiting maturation in the thymus (Miyazaki et al., J. Exp. Med. (1999) 189:413-422, the content of which is incorporated by reference in its entirety).

Furthermore, Cd5l has been shown to support the survival and the phagocytic activity of macrophages in liver inflammatory (hepatitis) lesions (Haruta et al., J. Biol. Chem. (2001) 276:22910-22914, the content of which is incorporated by reference in its entirety). Cd5l has been shown to be responsible for the resistance to infection with the intracellular bacteria Listeria monocytogenes and macrophage survival and bacterial clearance in L. monocytogenes infection (Joseph et al. Cell (2004) 119:299-309, the content of which is incorporated by reference in its entirety). Cd5l has been shown to mediate protection of macrophages from the apoptotic effects of oxidized lipids, including oxidized low density lipoprotein (oxLDL). Cd5l has been shown to facilitate cellular adhesion, promotion of lipid accumulation through enhanced CD36-mediated uptake of oxLDL, and macrophage survival within atherosclerotic lesions (Arai et al., Cell Metab. (2005) 1:201-213; Amézaga et al., J. Leukoc. Biol. (2014) 95(3):509-20, the contents of which are incorporated by reference in their entireties). Consequently, up-regulation of Cd5l inhibits immune cell apoptosis and strengthens innate immune response, for example, at lesion sites. And increasing the expression level of Cd5l can be used to treat a human subject with a disease (e.g., an age-related disease) caused by a decreased expression level of Cd5l, a human subject having a decreased expression of Cd5l, or any combination thereof.

Cd5l-induced lipolysis (the breakdown of fats and other lipids by hydrolysis to release fatty acids) occurs with progression of obesity. Cd5l participates in obesity-associated inflammation following recruitment of inflammatory macrophages into adipose tissues, a cause of insulin resistance and obesity-related metabolic disease (Kurokawa, J., et al., (2011). Cd5l is involved in obesity-associated recruitment of inflammatory macrophages into adipose tissue. Proceedings of the National Academy of Sciences of the United States of America, 108(29), 12072-12077. http://doi.org/10.1073/pnas.1101841108, the content of which is incorporated by reference in its entirety). Increase in blood Cd5l has been shown to be a critical event for the initiation of macrophage recruitment into adipose tissue, which is followed by insulin resistance.

Regulation of intracellular lipids mediated by Cd5l has a direct effect on transcription regulation mediated by nuclear receptors ROR-gamma-t (also referred to as RORγt or RORγ2), encoded by the RORC gene (Wang, C., et al., (2015). Cd5l/AIM regulates lipid biosythesis and restrains Th17 cell pathogenicity. Cell, 163(6):1413-1427. http://doi.org/10.1016/j.cell.2015.10.068; the content of each is incorporated by reference in its entirety). Th17 cells play an important role in host defense against extracellular pathogens and tissue homeostasis but can induce autoimmunity by balancing “pathogenic” and “non-pathogenic” Th17 cell states. Cd5l has been shown to be a regulator expressed in non-pathogenic, but not in pathogenic Th17 cells. Although Cd5l does not affect Th17 differentiation, it is a functional switch that regulates the pathogenicity of Th17 cells. Loss of Cd5l and downregulation of Cd5l can convert non-pathogenic Th17 cells into pathogenic cells that induce autoimmunity. CD5L mediates this effect by modulating the intracellular lipidome, altering fatty acid composition and restricting cholesterol biosynthesis and, thus, ligand availability for Rorγt, the master transcription factor of Th17 cells. Cd5l has been identified as a critical regulator of the Th17 cell functional state. Lipid metabolism has been shown to be important in balancing immune protection and disease induced by T cells.

Cd5l acts as a key regulator of metabolic switch in T-helper (Th)17 cells (Gaublomme, et al., (2015). Single-cell Genomics Unveils Critical Regulators of Th17 cell Pathogenicity. Cell, 163(6):1400-1412. http://doi.org/10.1016/j.cell.2015.11.009, the content of which is incorporated by reference in its entirety). Cd5l regulates the expression of pro-inflammatory genes in Th17 cells by altering the lipid content and limiting synthesis of cholesterol ligand of RORγt, the master transcription factor of Th17-cell differentiation.

Cd5l is mainly present in non-pathogenic Th17 cells, where it decreases the level of polyunsaturated fatty acyls (PUFA), affecting two metabolic proteins, MSMO1 and CYP51A1. MSMO1 and CYP51A1 synthesize ligands of RORγt (which can also be ligands of RORγ (also referred to as RORγ1), an isoform of RORγt also encoded by the same RORC. Cd5l can thus limit the activity of RORγt, resulting in decrease expression of pro-inflammatory genes.

Cd5l participates in obesity-associated autoimmunity via its association with IgM, interfering with the binding of IgM to Fcalpha/mu receptor and enhancing the development of long-lived plasma cells that produce high-affinity IgG autoantibodies (PubMed:23562157, the content of which is incorporated by reference in its entirety).

Perp

Perp is an important mediator of stratified epithelial development, cell adhesion, and apoptosis through desmosomal activities. Perp has been shown to be a p53 transcriptional target pro-apoptotic gene expressed in high levels during apoptosis (Ihrie et al., Current Biology (2003) 13(22):1985-1990; Nowak et al., Cell Death and Differentiation (2005) 12(1):52-64; the content of each is incorporated by reference in its entirety). Perp is an apoptosis-associated target of p53. Perp has been shown to contribute to radiation-induced apoptosis in CD4⁺CD8⁺ thymocytes which undergo p53-dependent apoptotic response (Ihrie et al., Current Biology (2003) 13(22):1985-1990; Lowe et al., Nature (1993) 362(6423):847-849; the content of each is incorporated by reference in its entirety). Perp induction has been linked to p53-dependent apoptosis, and Perp has been shown to be an effector of p53-dependent apoptosis (Attardi et al., Genes Dev. (2000) 14(6):704-18, the content of which is incorporated by reference in its entirety). Perp has been observed to lead to an enhanced activity of the second mitochondria-derived activator of caspase (Smac) cascade (Chen et al., Cancer Biol. Ther. (2011) 12(12):1114-9, the content of which is incorporated by reference in its entirety). Smac promotes caspases-9 activation. Caspase-9 is an initiator caspase, and is activated and required during apoptosis. Thus, increasing the expression level of Perp can increase apoptosis in a human subject with an insufficient level of apoptosis, for example, caused by a decreased expression of Perp. Increasing the expression level of Perp in a human subject in needs thereof may be desirable, for example, a human subject having a disease-related decreased expression level of Perp.

Proper cell-cell adhesion in the skin requires the presence of multiple adhesion complexes, including adherens junctions, desmosomes, and tight junctions (Fuchs and Raghavan, Nat Rev Genet. (2002) 3(3):199-209, the content of which is incorporated by reference in its entirety). A fundamental role for Perp in promoting cell-cell adhesion and maintaining epithelial integrity. Desmosomes are cell-cell adhesive organelles with a role in forming strong intercellular adhesion during embryogenesis and in adult tissues subject to mechanical stress, such as the heart and skin. More recently, desmosome components have also emerged as cell signaling regulators. Loss of expression or interference with the function of desmosome molecules results in diseases of the heart and skin and contributes to cancer progression. (Broussard, J. A., et al., Cell Tissue Res (2015) 360: 501, the content of which is incorporated by reference in its entirety). For example, certain desmosome associated disorders are characterized by dysfunction of intercellular junctions of epithelia and cardiac muscle; dysfunction in the structural integrity of tissues; mutations in genes encoding desmosomal proteins resulting in heart disease and disorders of the skin and hair; autoimmune skin blistering disease that is caused by autoantibodies against desmogleins, membrane-spanning proteins of desmosomes; and cancer.

Perp is a known component in proper desmosome function. Studies have shown mice deficient for other desmosomal components exhibit blistering symptoms histologically similar to those seen in Perp^(−/−) mice (Koch et al. J Cell Biol (1997) 137:1091-1102, the content of which is incorporated by reference in its entirety). Moreover, the desmosomal cadherins desmoglein 1 and 3 are the primary antigens in the human autoimmune blistering diseases Pemphigus foliaceus and Pemphigus vulgaris, respectively, and patients with these diseases also develop blisters resembling those in Perp^(−/−) mice (Green and Gaudry, Nat Rev Mol Cell Biol. (2000) 1(3):208-16, the content of which is incorporated herein by reference in its entirety).

Perp has been shown to be required for Salmonella-induced inflammation (Hallstrom et al., Cell Microbiol. (2015) 17(6):843-59, the content of which is incorporated by reference in its entirety). Perp has been linked to human longevity (Flachsbart et al., Mutat. Res. (2010) 694(1-2):13-9, the content of which is incorporated by reference in its entirety). Thus, increasing the expression level of Perp can be used to treat a human subject with a disease (e.g., an age-related disease) caused by or associated with a decreased expression level of Perp, a human subject having a decreased expression of Perp, or any combination thereof.

Perp is a putative tumor suppressor gene and is downregulated in metastasizing cells, mammary carcinoma cells, and tumor tissues (Hildebrandt et al., Anticancer Res. (2000) 20(5A):2801-9, the content of which is incorporated by reference in its entirety). Downregulation of Perp has been reported in tumors of the ovary, uterus and breast, and in cutaneous melanoma, pancreas and mammary carcinoma cell lines, compared with the respective normal tissues and non-metastasizing cell lines. Loss of heterozygosity for Perp has been shown in cell lines derived from melanoma, breast, pancreas, cervical, prostate and colon carcinoma. Perp has been shown to be significantly downregulated in aggressive monosomy-3 type primary uveal melanoma (UM) tumors, compared to less aggressive disomy-3 type (Davies et al., J. Cell. Mol. Med. (2009) 13:1995-2007; Paraoan et al, Exp. Eye. Res. (2006) 83(4):911-9, the contents of which are incorporated by reference in their entireties). Perp expression has been shown to stabilize active p53, thus p53-regulated apoptosis, via modulation of p53-MDM2 interaction in uveal melanoma cells (Davies et al., Cell Death and Disease (2011) 2:e136, the content of which is incorporated by reference in its entirety).

In some embodiments, Perp's specific role within the framework of the p63 developmental program for stratified epithelia is in establishing cell-cell adhesive contacts. In particular, Perp localizes to desmosomes and is required for proper desmosome formation in stratified epithelia, as demonstrated by the abnormal morphology of desmosomes and the altered properties of desmosomal components in Perp^(−/−) skin. Perp's contribution to desmosomal integrity could be as a core structural component or, alternately, as a chaperone that facilitates the transit of other critical desmosome components to the plasma membrane. For example, Perp assists in the trafficking or assembly of desmosomal subunits. In the case of adherens junction complexes, β-catenin acts as a molecular chauffeur for E-cadherin, facilitating its shuttling from the secretory pathway to the plasma membrane. (Ihrie et al., Current Biology (2003) 13(22):1985-1990, the content of which is incorporated by reference in its entirety).

Deficiency of Perp has been shown to alter mammary gland homeostasis and promote cancer (Dusek et al., Breast Cancer Res. (2012) 14(2):R65, the content of which is incorporated by reference in its entirety). Loss of Perp has been shown to promote tumorigenesis (Beaudry et al., PLoS Genet. (2010) 6(10): e1001168, the content of which is incorporated by reference in its entirety). For example, Perp is a tumor suppressor of skin cancer. The lack of Perp has been shown to impair cell adhesion as a result of aberrant desmosome assembly, thereby diminishing tumor development (Marques et al., Cancer Res. (2005) 65:6551-6, the content of which is incorporated by reference in its entirety).

Squamous cell carcinoma (SCC) is a malignant proliferation of the keratinocyte of the epidermis. Perp has been reported to be downregulated during SCC progression, and Perp deficiency has been reported to promote SCC (Beaudry et al., PLoS Genet. (2010) 6(10): e1001168, the content of which is incorporated by reference in its entirety). The loss of Perp expression has been reported to correlate with the progression of oral cavity SCC with increased local relapse (Kong et al., Oral Surg. Oral Med. Oral Pathol. Oral Radiol. (2013) 115(1):95-103, the content of which is incorporated by reference in its entirety). Thus, increasing the expression level of Perp can be used to treat a human subject with cancer such as SCC or oral cavity SCC.

Perp has been shown to be a target of the p53-related transcription factor, p63, involved in maintaining epithelial integrity by promoting desmosomal cell-cell adhesion (Ihrie et al., Cell (2005) 120(6):843-56, the content of which is incorporated by reference in its entirety). Lack of Perp can result in postnatal lethality accompanied by dramatic blisters throughout their stratified epithelia, including the oral mucosa and skin, possibly because of a reduction in desmosome number and compromised desmosome complex formation. Thus, Perp is a critical component of the desmosome in the skin and other stratified epithelia.

Decreased Perp expression level has been shown in peripheral blood mononuclear cells from human subjects with rheumatoid arthritis, and this decreased Perp expression negatively correlates with severity and progression of rheumatoid arthritis (Du et al., Clinical and Developmental Immunology (2013) 2013:256462, the content of which is incorporated by reference in its entirety). And Perp may prohibit rheumatoid arthritis by regulating interleukin (IL)-17, which participates in the inflammatory process and disease activity of rheumatoid arthritis (Kohno et al., Modern Rheumatology (2008) 18(1):15-22, the content of which is incorporated by reference in its entirety). Loss of Perp has been shown to enhance the phenotypic effects of Pemphigus vulgaris, an autoimmune bullous disease in which autoantibodies against proteins of the desmosomal adhesion complex perturb desmosomal function, leading to intercellular adhesion defects in the oral mucosa and skin (Nguyen et al., J. Invest. Dermatol. (2009) 129(7):1710-8, the content of which is incorporated by reference in its entirety). Thus, increasing the expression level of Perp can be used to treat a human subject with an autoimmune disease such as rheumatoid arthritis.

Unc5b

Unc5b is also known as Unc5h2. Down-regulation of Unc5b has been shown to significantly inhibit apoptosis (He et al., Mol. Biol. Cell. (2011) 22(11):1943-54, the content of which is incorporated by reference in its entirety). Thus, increasing the expression level of Unc5b can increase apoptosis in a human subject with an insufficient level of apoptosis, possibly caused by a decreased expression of Unc5b. Increasing the expression level of Unc5b can increase the expression level of Unc5b in a human subject who needs an increased expression level of Unc5b, for example, a human subject having a disease-related decrease in the expression level of Unc5b.

The expression of Unc5b has been shown to be downregulated in multiple cancers, including colorectal, breast, ovary, uterus, stomach, lung, and kidney cancers (Thiebault et al., Proc. Natl. Acad. Sci. U.S.A. (2003) 100(7):4173-8, the content of which is incorporated by reference in its entirety). Unc5b has been shown to mediate p53-dependent apoptosis through death-associated protein kinase (DAP-kinase) (Llambi et al., EMBO J. (2005) 24(6):1192-201; Arakawa, Cell Death Differ. (2005) 12(8):1057-65, the contents of which are incorporated by reference in their entireties). Up-regulation of Unc5b has been reported to be associated with the antimelanoma effect of IFN-gamma (Gollob et al., Cancer Res. (2005) 65(19):8869-77, the content of which is incorporated by reference in its entirety).

Decreased Unc5b expression has been observed in bladder cancer cells (Liu et al., BMC Cancer. (2014) 14: 93, the content of which is incorporated by reference in its entirety). Decreased Unc5b expression has been shown in prostate carcinoma cells (Kong et al., Tumour Biol. (2013) 34(5):2765-72, the content of which is incorporated by reference in its entirety). It has been shown that Unc5b emerged more in bladder cancer cells with lower degrees of malignancy than those with higher degrees of malignancy; Unc5b expression in bladder cancer cells was significantly reduced compared to normal bladder cells, and low Unc5b expression was an independent risk factor for postoperative recurrence in patients with different stages and grades bladder cancer (Liu et al., Tumour Biol. (2013) 34(4):2099-108, the content of which is incorporated by reference in its entirety). Unc5b mRNA has been shown to be down-expressed in bladder cancer tissues. Furthermore, human subjects with lower Unc5b expression in tumors have been shown to have significantly higher recurrence rate after curative surgery and poorer prognosis than those with higher Unc5b expression. Unc5b has been shown to be downregulated in kidney carcinoma (Zhan et al., Tumour Biol. (2013) 34(3):1759-66, the content of which is incorporated by reference in its entirety).

Further, Unc5b mRNA expression has been shown to decrease in some colorectal cancer human subjects, and the human subjects with low-Unc5b-expression tumors showed a significantly higher recurrence rate after curative surgery (Okazaki et al., Int. J. Oncol. (2012) 40(1):209-16, the content of which is incorporated by reference in its entirety). Thus, increasing the expression level of Unc5b can be used to treat a human subject with cancer.

Bag5

Bag5 has been shown to function as the nucleotide exchange factor of Hsp70 for the enhancement of protein refolding (Arakawa et al. Structure (2010) 18(3):309-19, the content of which is incorporated by reference in its entirety). Bag5 has been shown to directly interacted with mutations in PTEN-induced kinase 1 (PINK1), and regulated PINK1 degradation via ubiquitin proteasome system (UPS) (Wang et al., PLoS One. (2014) 9(1):e86276, the content of which is incorporated by reference in its entirety). Loss of the stability of PINK1 may contribute to sporadic Parkinson's disease (PD). Bag5 has been reported to protect mitochondria against MPP+− and rotenone-induced oxidative stress. Thus, increasing the expression level of Bag5 can be used to treat a human subject with an age-related disease caused by a decreased expression level of Bag5, a human subject having a decreased expression of Bag5, or any combination thereof.

Bag5 has been reported to be linked to non-Hodgkin lymphoma (Kelly et al., Cancer Epidemiol. Biomarkers. Prev. (2010) 19(11):2847-2858, the content of which is incorporated by reference in its entirety). Thus, increasing the expression level of Bag5 can be used to treat a human subject with cancer such as non-Hodgkin lymphoma.

Bri3

Increasing the expression level of Bri3 in a human subject in needs thereof may be desirable, for example, a human subject having a disease-related decreased expression level of Bri3.

Reducing Bri3 expression has been shown to increase beta-amyloid (referred to in various literature references, and in this application, as beta-amyloid, β-amyloid, βA, amyloid-beta, Abeta, and/or Aβ) secretion (Matsuda et al, J. Biol. Chem. (2009) 284(23):15815-25, the content of which is incorporated by reference in its entirety). βA is the main component of the amyloid plaques found in the brains of Alzheimer patients. Bri3 has been shown to interact with amyloid precursor protein (APP) and inhibits APP processing (Matsuda et al., J. Biol. Chem. (2005) 280(32):28912-6; Matsuda et al., J. Neurosci. (2008) 28(35):8668-76; Fotinopoulou et al., J. Biol. Chem. (2005) 280(35):30768-72, the contents of which are incorporated by reference in their entireties). Specifically, Bri3 overexpression reduces both α- and β-amyloid precursor protein (αAPP and βAPP) cleavage and formation of βA. Thus, Bri3 expression or overexpression can reduce βAPP cleavage into βA. Reduced βAPP cleavage into βA can inhibit or reduce amyloid plaque deposition. Reducing amyloid plaque deposition can inhibit, suppress, prevent, or reverse AD or symptoms related to AD. Furthermore, Bri3 does not cause the massive accumulation of cleaved APP C-terminal fragment in some subjects (Matsuda et al).

In Alzheimer's disease (AD), the amyloidogenic pathway generating βA starts by β-secretase cleavage of β-amyloid precursor protein (βAPP) at the EVKM⁶⁵²↓DA sequence. Bri3 and BACE1 co-immunoprecipitate and co-localize in neurons from normal human and mouse brain. Furthermore, similar results were seen in human samples from patients with AD and in brains from a mouse model of the disease. (Wickham, L., et al. (2005), β-Amyloid protein converting enzyme 1 and brain-specific type II membrane protein BRI3: binding partners processed by furin. Journal of Neurochemistry, 92:93-102. doi:10.1111/j.1471-4159.2004.02840.x, the content of which is incorporated by reference in its entirety). Bri3 expression is inversely related to APP cleavage to βA (and thereby to amyloid plaque deposition).

Disclosed herein is a method of inhibiting amyloid plaque deposition in an individual, either known or suspected to exhibit falling levels of Bri3 expression, by administering an agent known to increase Bri3 expression. In one embodiment, the method comprises selecting the individual by monitoring Bri3 expression over time thereby confirming that the levels of Bri3 expression are indeed decreasing. In another embodiment, the method comprises selecting the individual by identifying the presence of one or more risk factors associated with amyloid plaque deposition and consequently decreased Bri3 expression; the risk factors may be selected from the individual's age, family history, health conditions, medical history, or habits In some embodiments, the method comprises selecting the individual both by monitoring Bri3 expression over time, and by identifying one or more risk factors. In certain embodiments, the agent known to increase Bri3 expression is a nitroxide antioxidant, and more particularly, in some embodiments, the agent is Tempol. Consequently, by administering an agent known to increase Bri3 expression, the method can inhibit amyloid plaque deposition in the individual known or suspected to exhibit falling levels of Bri3 expression—by inhibiting amyloid precursor protein processing, leading to decreased production and deposition of βA.

Cardiovascular disease (CVD) and Alzheimer disease (AD) are 2 major causes of morbidity and mortality and represent formidable medical and societal challenges. The classical pathological signature of AD is the deposition of amyloid-rich plaques in the brain. βA is a key constituent of these plaques, and its deposition in the brain has been strongly implicated in the pathogenesis of AD. βA proteins are generated from βAPP, a trans-membrane glycoprotein that is sequentially processed by beta- and gamma-secretases to release βA proteins. These βA proteins are hydrophobic monomers, consisting of 39 to 42 amino acids, the most common of which are βA40 and βA42. βA proteins circulate in the plasma and cerebrospinal fluid, βA40 being the most abundant. The longer form, βA42, is most abundant in the classic cerebral plaques of AD, whereas βA40 is the more abundant form in the vascular wall and in platelets. (B. Williams, Amyloid Beta and Cardiovascular Disease. Journal of the American College of Cardiology March 2015, 65 (9) 917-919; DOI: 10.1016/j.jacc.2015.01.013, the content of which is incorporated by reference in its entirety).

Bri3 has been shown to exhibit the ability to stabilize the microtubule network and attenuate the microtubule-destabilizing activity of SCG10 (Gong et al., BMB Rep. (2008) 41(4):287-93, the content of which is incorporated by reference in its entirety). Thus, Bri3 is a critical component of the desmosome in the skin and other stratified epithelia.

Overexpression of Bri3 has been reported to induce apoptosis, possibly through lysosome (Wu et al., Biochem. Biophys. Res. Commun. (2003) 311(2):518-24, the content of which is incorporated by reference in its entirety). Bri3 has also been reported to be down-regulated with colorectal cancer progression (Bandrés et al., Oncology Reports (2007) 17(5):1089-1094, the content of which is incorporated by reference in its entirety). Thus, increasing the expression level of Bri3 can be used to treat a human subject with cancer.

Improved Re-Epithelization

Wound healing is mediated by desmosome activity regarding cellular adhesion. Generally, addressing tissue damage involves activities to facilitate natural biological processes, such as cleaning the damaged area and preventing further damage due to objects contacting the damaged area. Reduced rates or reepithelization may be based on an individual's predisposition to decreased tissue repair and the associate biological processes. External and environmental factors affecting desmosome function and angiogenesis manifest negatively in reduced re-epithelization and wound repair. For example, an individual genetically predisposed to diminished or decreased Perp expression will present with reduced rates of reepithelization and wound repair.

Tissues such as cardiac muscle and epidermis are extremely resistant to shearing forces and physical stress. A vital contributing factor in stress resistance is strong intercellular adhesion mediated by cell-cell junctions. Among these is the desmosome, which is particularly abundant in tissues that are subject to stress. Analysis of human autoimmune and genetic disease, and targeted deletions of desmosomal genes in mice shows that abnormality of desmosomes leads to tissue disruption. (Hyper-adhesion in desmosomes: its regulation in wound healing and possible relationship to cadherin crystal structure, David R. Garrod, et al., Journal of Cell Science 2005 118: 5743-5754; doi: 10.1242/jcs.02700, the content of which is incorporated by reference in its entirety).

The resistance of tissues to physical stress is dependent upon strong cell-cell adhesion in which desmosomes play a crucial role. We propose that desmosomes fulfil this function by adopting a more strongly adhesive state, hyper-adhesion, than other junctions. Formation of intercellular adhesion appears to be initiated by adherens junctions and subsequently reinforced by desmosomes (Vasioukhin et al., 2000). The essential nature of desmosomal reinforcement is demonstrated by the loss of epidermal integrity, which occurs following conditional knockout of the desmosomal plaque protein desmoplakin from the epidermis (Vasioukhin et al., 2001). Thus it appears that desmosomes are of prime importance for maintaining tissue integrity. (Garrod et al., 2005).

Proper enamel formation requires desmosome mediated cellular adhesion. Teeth develop from the tooth germ, which is an aggregation of cells derived from the first branchial arch and the neural crest. The tooth germ is composed of the enamel organ, the dental papilla, and the dental follicle. Moreover, the enamel organ is composed of the outer enamel epithelium, inner enamel epithelium, stellate reticulum, and stratum intermedium and gives rise to ameloblasts, which produce enamel and become a part of the reduced enamel epithelium. In developing teeth, nectin-1 and -3 are strongly expressed at the interface between the maturation-stage ameloblasts and the underlying cells of the stratum intermedium (Barron et al., 2008; Yoshida et al., 2010). Nectin-1-deficient mice exhibit defective amelogenesis of their incisor teeth, which are prone to wear and breakage. This defect appears to result from loss of adhesive contact between mature ameloblasts and the underlying stratum intermedium. At this interface in wild-type mice, numerous, large desmosomes are present; however, in the mutant mice, the desmosomes are smaller and less numerous. Thus, nectin-1 regulates desmosome assembly and is required for normal enamel mineralization (Barron et al., 2008). Cellular Adhesion in Development and Disease Kenji M. et al., in Current Topics in Developmental Biology, 2015

Enamel defects in mice carrying compound mutations of cell-cell adhesion molecules Nectin-1 and -3, as well as mice lacking the cell membrane protein Perp, indicate the importance of the integrity of the ameloblast cell layer and its tight contacts with the SI cell layer (Jheon et al., 2011; Neupane et al., 2014; Yoshida, Miyoshi, Takai, & Thesleff, 2010). The SI consists of a few layers of epithelial cells adjacent to the ameloblasts. Ameloblasts and SI cells are tightly bound by desmosomes, recruited by interaction between Nectin-1 expressed in ameloblasts and Nectin-3 in SI cells (Yoshida et al., 2010).

Some embodiments disclosed herein provide for a method of treating, promoting, and desmosome activity including cell adhesion and re-epithelialization. For example, in some embodiments, administering to a human subject an effective amount of the nitroxide antioxidant results in an increased expression level of Perp.

Administration of the nitroxide antioxidant may be through direct contact between the nitroxide antioxidant and the target area. For example, topical application of the nitroxide onto the human subject at a location determined to have one or more tissue damage. Such treatment of the human subject with the effective amount of the nitroxide antioxidant can result in an increased expression level of the gene. For example, the treatment can result in increased expression levels of Cd5l, Perp, Unc5b, Bag5, Bri3, or any combination thereof. The increased expression levels of Cd5l, Perp, Unc5b, Bag5, Bri3, or any combination thereof, can increase the level of apoptosis. The increased level of apoptosis can result in a decrease in or disappearance of signs and symptoms of the tissue damage or dysfunction desmosome activity. For example, the rate of reepithelization of the damaged tissue is decreased relative to natural biological processes. Another example provides for improved enamel formation, where the human subject is predisposed or at risk for dysfunctional amelogenesis

In some embodiments, the nitroxide antioxidant is prepared in a composition suitable for topical application. An absorbent material may be saturated with the nitroxide antioxidant and applied directly to the target area. In another embodiment, the absorbent material may have one or more adhesive portions to facilitate a positive attachment with the human subject. For example, Tempol is applied first to an adhesive bandage and then the saturated adhesive bandage is applied onto the skin of a human subject at a location, where the skin has been damaged. Damaged tissue may be identified as a result of physical forces which have compromised the integrity of one or more layers of the dermis.

Methods for Counteracting Decrease in Gene Expression or Treating a Condition Related to Decrease in Gene Expression

Some embodiments disclosed herein provide methods for counteracting decrease in gene expression (e.g., age-related decrease in gene expression) or treating a disease (e.g., an age-related disease), comprising administering to a human subject an effective amount of a nitroxide antioxidant. In some embodiments, the methods further comprise: identifying the human subject (e.g., a human subject over the age of 35). In some embodiments, the human subject has a decreased expression level of one or more genes (e.g., genes associated with the apoptosis pathway or an age-related disease). In some embodiments, the methods comprise determining the expression level of one or more genes (e.g., genes associated with the apoptosis pathway). However, this may not be necessary in some instances, such as where a decreased expression level of one or more genes associated with the apoptosis pathway can be inferred from the human subject's age, family history, health conditions, medical history, habits, or a combination thereof. In some embodiments, the methods disclosed herein may be used to treat a human subject shows no symptoms of an age-related disease, but is at risk of having an age-related disease. Exemplary risk factors for an age-related disease include, but are not limited to, age, family history, health conditions, medical history, habits, or a combination thereof. In some embodiments, risk factors for an age-related disease comprise a decreased expression level of one or more genes associated with the apoptosis pathway. Thus, in some embodiments, the methods comprise administering a nitroxide antioxidant to a human subject suspected to have a decreased expression level of one or more genes, or at risk of developing a decreased expression level of one or more genes (e.g., genes associated with the apoptosis pathway or an age-related disease)—but not known to have such a decreased expression level. The suspicion and/or risk may be inferred from the subject's medical history and/or age.

In some embodiments, administering to the human subject an effective amount of the nitroxide antioxidant results in an increased expression level of a gene, for example a gene associated with the apoptosis pathway. The gene associated with the apoptosis pathway can be Cd5l, Perp, Unc5b, Bag5 or Bri3. The treatment of the human subject with the effective amount of the nitroxide antioxidant can result in an increased expression level of the gene. For example, the treatment can result in increased expression levels of Cd5l, Perp, Unc5b, Bag5, Bri3, or any combination thereof. The increased expression levels of Cd5l, Perp, Unc5b, Bag5, Bri3, or any combination thereof, can increase the level of apoptosis. The increased level of apoptosis can result in a decrease in or disappearance of signs and symptoms of an age-related disease associated with decreased apoptosis, including the curing of the age-related disease. In some embodiments, the increased expression levels of Cd5l, Perp, Unc5b, Bag5, Bri3, or any combination thereof, can decrease the level of apoptosis. The decreased level of apoptosis can result in a decrease in or disappearance of signs and symptoms of the age-related disease associated with increased apoptosis, including the curing of the disease associated with age-related disease associated with increased apoptosis.

Methods for Treating Autoimmune Diseases

Some embodiments disclosed herein provide methods for treating an autoimmune disease in a human subject in need thereof, comprising identifying a human subject having an autoimmune disease and in need of an increased expression level of a gene associated with the apoptosis pathway; and administering to the human subject an effective amount of a nitroxide antioxidant. In some embodiments, the methods disclosed herein may be used to treat a human subject shows no symptoms of an autoimmune disease, but is at risk of having an autoimmune disease. Exemplary risk factors for an autoimmune disease include, but are not limited to, age, family history, health conditions, medical history, habits, or a combination thereof. In some embodiments, risk factors for an autoimmune disease comprise a decreased expression level of one or more genes associated with the apoptosis pathway.

Autoimmunity is the system of immune responses of an organism against its own healthy cells and tissues. Any disease that results from such an aberrant immune response can be termed an “autoimmune disease.” Non-limiting examples of autoimmunity include celiac disease, diabetes mellitus type 1, sarcoidosis, systemic lupus erythematosus (SLE), Sjögren's syndrome, eosinophilic granulomatosis with polyangiitis, Hashimoto's thyroiditis, Graves' disease, idiopathic thrombocytopenic purpura, Addison's disease, rheumatoid arthritis (RA), ankylosing spondylitis, polymyositis (PM), and dermatomyositis (DM). Autoimmune diseases are very often treated with steroids

T cells play a role in human diseases. For example, T-helper 17 (Th17) cells, a unique CD4+ T-cell subset characterized by production of interleukin-17 (IL-17), play a role in human diseases. IL-17 is a highly inflammatory cytokine with robust effects on stromal cells in many tissues. Recent data in humans and mice suggest that Th17 cells play an important role in the pathogenesis of a diverse group of immune-mediated diseases, including psoriasis, rheumatoid arthritis, multiple sclerosis, inflammatory bowel disease, and asthma. Data indicate that Th17 cells may play a role in tumorigenesis and transplant rejection. Important differences, as well as many similarities, are emerging when the biology of Th17 cells in mice is compared with corresponding phenomena in humans. The understanding of human Th17 biology contributes to understanding of the mechanisms underlying many diseases, which involve cytokines, chemokines, and feedback mechanisms. A strong association between excessive Th17 activity and human disease has been shown. Disclosed herein are therapeutic methods targeting Th17 cells.

In some embodiments, the autoimmune disease is a manifestation of unregulated pathogenic activity of helper T-cells, mediated by one or more effector molecules. Helper T-cells are those differentiated from native CD4+ and classified in one or more subsets. Upon antigenic stimulation, naïve CD4+ T cells activate, expand and differentiate into different effector phenotypes. Th17 cells, which have been characterized as an additional effector T cell subset that produce interleukin (IL) glycoproteins IL-17A, IL-17F, IL-21 and IL-22, are known to be the critical driver of autoimmune tissue inflammation. Th17 has been identified as having non-pathogenic and pathogenic function in the presence of effector cells or effector molecules IL-1 beta, IL-6, and IL-23 (Ouyang, W., Kolls, J. K., & Zheng, Y. (2008). The Biological Functions of T Helper 17 Cell Effector Cytokines in Inflammation. Immunity, 28(4), 454-467. http://doi.org/10.1016/j.immuni.2008.03.004, the content of which is incorporated by reference in its entirety).

In some embodiments, the pathogenic function of Th17 is controlled though intracellular lipid concentrations. For example, expression of Cd5l maintains or decreases the level of polyunsaturated fatty acyls (PUFA. As a result, the modulated ratio of PUFA to SFA directly affects the binding and activity of the master transcription factor for TH17 differentiation, Rorγt. Decreased PUFA results in the decreased Rorγt transcription of promoters, ligand availability and binding affinity for pathogenic effectors IL-17 and IL-23/IL-23r (Rutz, S. Eidenschenk C., Kiefer J R., Ouyang W., (2016) Post-translational regulation of RORγt-A therapeutic target for the modulation of interleukin-17-mediated responses in autoimmune diseases Cytokine & Growth Factor Reviews 30, 1-17. https://doi.org/10.1016/j.cytogfr.2016.07.004, the content of which is incorporated by reference in its entirety).

In some embodiments, administering to a human subject an effective amount of the nitroxide antioxidant results in an altered lipidome and fatty acid composition within a Th17 cell. The treatment of the human subject with the effective amount of nitroxide can result in increased concentration and biosynthesis of PUFA. In some embodiments, increased PUFA concentration can reduce interaction with one or more effector molecules known to trigger a pathogenic response in the Th17 cell. For example, increased PUFA concentration inhibits ligand availability for IL-17 and IL-23. Decreased pathogenic effector molecule interaction inhibits pathogenic activity of the Th17 cell. For example, reduction of Th17 mediated autoimmune disease correlates with the reduced interaction of the pathogenic effector molecule interaction. In some embodiments, the decreased level of pathogenic effector molecule interaction can result in a decrease in or disappearance of signs and symptoms of the autoimmune disease, including the curing of the autoimmune disease. (Wang, C., et al., (2015)).

In some embodiments, the nitroxide antioxidant increases expression of one or more genes associated with lipid biosynthesis within the Th17 cell. For example, Cd5l alters cholesterol biosynthesis within Th17 cells. The alteration of the lipidome within the cell results in increased PUFA concentration and decreased IL-17 and IL-23 interaction. Where Cd5l is under expressed Th17 cells exhibit pathogenic activity. Increased expression of Cd5l inhibits or eliminates pathogenic activity of TH17 cells.

In some embodiments, administering to the human subject an effective amount of the nitroxide antioxidant results in an increased expression level of a gene, for example a gene associated with the apoptosis pathway. The gene associated with the apoptosis pathway can be Cd5l, Perp, Unc5b, Bag5 or Bri3. The treatment of the human subject with the effective amount of the nitroxide antioxidant can result in an increased expression level of the gene. For example, the treatment can result in increased expression levels of Cd5l, Perp, Unc5b, Bag5, Bri3, or any combination thereof. the increased expression levels of Cd5l, Perp, Unc5b, Bag5, Bri3, or any combination thereof, can increase the level of apoptosis. The increased level of apoptosis can result in a decrease in or disappearance of signs and symptoms of the autoimmune disease, including the curing of the autoimmune disease. In some embodiments, the increased expression levels of Cd5l, Perp, Unc5b, Bag5, Bri3, or any combination thereof, can decrease the level of apoptosis. The decreased level of apoptosis can result in a decrease in or disappearance of signs and symptoms of the autoimmune disease, including the curing of the autoimmune disease.

Compositions

The nitroxide antioxidant can be administered in the form of, for example, solid compositions, liquid compositions or other compositions for oral administration, injections, liniments or suppositories for parenteral administration.

Solid compositions for oral administration include compressed tablets, pills, capsules, dispersible powders and granules. Capsules include hard capsules and soft capsules. In such solid compositions, Tempol may be admixed with an excipient (e.g. lactose, mannitol, glucose, microcrystalline cellulose, starch), combining agents (hydroxypropyl cellulose, polyvinyl pyrrolidone or magnesium metasilicate aluminate), disintegrating agents (e.g. cellulose calcium glycolate), lubricating agents (e.g. magnesium stearate), stabilizing agents, agents to assist dissolution (e.g. glutamic acid or aspartic acid), or the like. The agents may, if desired, be coated with coating agents (e.g. sugar, gelatin, hydroxypropyl cellulose or hydroxypropylmethyl cellulose phthalate), or be coated with two or more films. Further, coating may include containment within capsules of absorbable materials such as gelatin.

Liquid compositions for oral administration include pharmaceutically acceptable solutions, suspensions, emulsions, syrups and elixirs. In such compositions, the nitroxide antioxidant is dissolved, suspended or emulsified in a commonly used diluent (e.g. purified water, ethanol or mixture thereof). Furthermore, such liquid compositions may also comprise wetting agents or suspending agents, emulsifying agents, sweetening agents, flavoring agents, perfuming agents, preserving agents, buffer agents, or the like.

Injections for parenteral administration include solutions, suspensions, emulsions and solids which are dissolved or suspended. For injections, the nitroxide antioxidant can be dissolved, suspended and emulsified in a solvent. The solvents include, for example, distilled water for injection, physiological salt solution, vegetable oil, propylene glycol, polyethylene glycol, alcohol such as ethanol, or a mixture thereof. Moreover the injections can also include stabilizing agents, agents to assist dissolution (e.g. glutamic acid, aspartic acid or POLYSORBATE80™), suspending agents, emulsifying agents, soothing agents, buffer agents, preserving agents, etc. They can be sterilized in the final process or manufactured and prepared by sterile procedure. They can also be manufactured in the form of sterile solid compositions, such as a freeze-dried composition, and they may be sterilized or dissolved immediately before use in sterile distilled water for injection or some other solvent.

Other compositions for parenteral administration include liquids for external use, and ointment, endermic liniments, inhale, spray, suppositories for rectal administration and pessaries for vaginal administration which comprise the nixtroxide antioxidant and are administered by methods known in the art.

Spray compositions can comprise additional substances other than diluents: e.g. stabilizing agents (e.g. sodium sulfite hydride), isotonic buffers (e.g. sodium chloride, sodium citrate or citric acid). A small aerosol particle size useful for effective distribution of the medicament can be obtained by employing self-propelling compositions containing the drugs in micronized form dispersed in a propellant composition. Effective dispersion of the finely divided drug particles can be accomplished with the use of very small quantities of a suspending agent, present as a coating on the micronized drug particles. Evaporation of the propellant from the aerosol particles after spraying from the aerosol container leaves finely divided drug particles coated with a fine film of the suspending agent. In the micronized form, the average particle size can be less than about 5 microns. The propellant composition may employ, as the suspending agent, a fatty alcohol such as oleyl alcohol. The minimum quantity of suspending agent can be approximately 0.1 to 0.2 percent by weight of the total composition. The amount of suspending agent can be less than about 4 percent by weight of the total composition to maintain an upper particle size limit of less than 10 microns or 5 microns. Propellants that may be employed include hydrofluoroalkane propellants and chlorofluorocarbon propellants. Dry powder inhalation may also be employed.

EXAMPLES

The following examples are offered to illustrate but not to limit the invention.

In order to facilitate understanding, the specific embodiments are provided to help interpret the technical proposal, that is, these embodiments are only for illustrative purposes, but not in any way to limit the scope of the invention.

Example 1. Effects of Tempol on Expression of Genes Associated with the Apoptosis Pathway

To assess the effects of Tempol on gene expression, Tempol was administered to experimental mice at a dose of 5 mg/g of food from 14 months to 31 months after birth. Mice receiving the same food without the addition of Tempol were used as a negative control. At the age of 31 months, the experimental animals were sacrificed and the hearts were surgically removed. The expression of a broad spectrum of genes in the cardiac tissue was assessed using chip-based microarray technology. Such chips are well known in the art and are widely used to assess gene expression. The experimental results showed that five genes associated with the apoptosis pathway, Cd5l, Perp, Unc5b, Bag5 and Bri3, exhibited statistically significant increase in expression. This result is shown in Table 1.

In at least some of the previously described embodiments, one or more elements used in an embodiment can interchangeably be used in another embodiment unless such a replacement is not technically feasible. It will be appreciated by those skilled in the art that various other omissions, additions and modifications may be made to the methods and structures described above without departing from the scope of the claimed subject matter. All such modifications and changes are intended to fall within the scope of the subject matter, as defined by the appended claims.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible sub-ranges and combinations of sub-ranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art all language such as “up to,” “at least,” “greater than,” “less than,” and the like include the number recited and refer to ranges which can be subsequently broken down into sub-ranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 articles refers to groups having 1, 2, or 3 articles. Similarly, a group having 1-5 articles refers to groups having 1, 2, 3, 4, or 5 articles, and so forth.

While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
